D-calycanthine has antifungal activity, it shows significant inhibitory activities against five plant pathogenic fungi Exserohilum turcicum, Bipolaris maydis, Alternaria solani, Sclerotinia sderotiorum, and Fusarium oxysportium.

The structures of the two compounds were established by (1)H- and (13)C-NMR, and MS (FAB, ESI) analyses. In the in vitro tests, compounds 1 and 2 showed significant inhibitory activities against five plant pathogenic fungi Exserohilum turcicum, Bipolaris maydis, Alternaria solani, Sclerotinia sderotiorum, and Fusarium oxysportium, among which B. maydis was found to be the most susceptible to 1 with an EC(50) value of 29.3 microg/ml, followed by S. sderotiorum to 2 with an EC(50) value of 61.2 microg/ml.
